Re: Inspiron 1545- replacing hard drive, new SATA drive not found "Internal Hard Disk Drive Not Found
I suggest you to update the BIOS to the latest version available on the drivers download page and check if the hard drive is recognized properly. We have officially tested this system with the maximum hard drive capacity of 640GB. Please use a hard drive with a capacity of 640GB or lesser, if you experience the same issue after the BIOS update.
Let me know about your findings.
